US politicians have made little progress on legislation that would provide more than $7bn in healthcare for emergency workers and others who became ill after breathing in dust and toxic fumes at the site of the September 11 attacks.

A bill was approved by the US House of Representatives in September, but Republicans in the Senate have consistently blocked discussion because of a deadlock over tax-cut extensions.
